Use bidirectional text in Keynote on iPad
Keynote also supports bidirectional text, so you can enter and edit text written from left to right (such as in English or Chinese) and from right to left (such as in Arabic or Hebrew). You can use bidirectional text in paragraphs, shapes, and table cells.
Note: You can use any Keynote theme to create a bidirectional presentation, but to see themes designed specifically for another language, you must set the primary language of your computer to that language (go to Settings > General > Language & Region, then set the language). When you create a new presentation, you see themes for that language.
